The ultimate in functionality, precision, and control, the Cosman UnifiedTM (CU) is a sterile-packed, tissue-piercing RF cannula/electrode with a long fluid injection line and thermocouple (TC) temperature sensor. The CU simplifies RF procedures, inventory control, and sterilization logistics. Its fluid line helps maintain electrode position during injection to optimize control of lesion position and size. Its unique design is protected by U.S. Patent 7,862,563.

Each disposable CR injection electrode has a 5 mm active tip and typically is used for non-temperature-controlled radiofrequency (RF) facet denervations. Each probe comes sterile-packed and is tissue-piercing to eliminate the need for introducer cannulae. Its long, flexible fluid line enables the physican to keep his/her hands out of the x-ray beam while administering contrast medium or anesthetic, and reduces disruption of the needle position during injection.

Each disposable CP injection electrode has a 1 mm active tip and typically is used for stimulation-guided blocks, in which a nerve stimulation signal is first applied to position the electrode, and then anesthetic solution is injection to block the nerve. Each probe come sterile-packed and is tissue-piercing. Its long, flexible fluid line enables the physican to keep his/her hands out of the x-ray beam while administering contrast medium, and reduces disruption of the needle position during injection.
